Abstract

Elevated colonic luminal serine-protease (Ser-P) activity of diarrhea-predominant IBS (IBS-D) patients evokes a proteinase-activated receptor (PAR)-2-mediated colonic hypersensitivity in mice. Despite similarly elevated Ser-P levels in feces, patients with IBD exhibit visceral hypo- or normosensitivity to rectal distension, as opposed to IBS-D. To explain these discrepancies we studied the effect of colonic infusion of fecal supernatants from ulcerative colitis (UC) patients to colorectal mechanical sensitivity of mice and explored the involvement of PAR-4 and its activator Cathepsin-G (Cat-G). Fecal protease activities were assayed in healthy subjects, IBS-D and UC patients in presence or not of antiproteases or Cat-G inhibitor. Following intracolonic infusion of fecal supernatants from healthy subjects, IBS-D and UC patients or PAR-4 activating peptide (PAR-4-AP) or Cat-G, EMG response to colorectal balloon distension was recorded in mice. This nociceptive response was also determined after treatment with pepducin (PAR-4 antagonist) on UC supernatant or after a preincubation with antiproteases or Cat-G inhibitor. In contrast to IBS-D supernatant, UC supernatant promoted colonic hyposensitivity to distension, an effect mimicked by PAR-4-AP or Cat-G. UC supernatant-induced hypoalgesia was inhibited by a cocktail of antiproteases. However, blockade of PAR-4 or Cat-G inhibition resulted in colonic hypersensitivity similar to that observed after IBS-D supernatant infusion. Despite similarly elevated Ser-P activities, IBS-D and UC fecal supernatant display visceral pro- and antinociceptive effects in mice, respectively. Visceral hyposensitivity induced by fecal supernatant from UC patients results from PAR-4 activation by cathepsin-G, counterbalancing the pronociceptive effect of simultaneous PAR-2 activation.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
